HAND VACUUM-CLEANER.

Specification of Letters atent. Application filed February 16, 1909.

To all whom it' may concern.'

Be it known that l, CHARLES G. HU'roniN- son, a citizen ot the United States, residing at New York, in the county of New York and State of New York, have invented certain new and useful Improvements in. Hand Vacuuirl-Cleaners, of which the following is a specification, reference being had therein to the acconnninyingl drawing.

My invention relates especially to that class of devices employed tor ren'loving` dust and dirt from carpets, rugs, upholstery, curtains, walls, etc., and has tor'its object the provision of a simple, cheap and effective hand vacuum cleaner which may be oper ated by one person.

To attain the desired end, my invention consists in certain novel and useful combinations or arrangements of parts, and peculiaritics of construction and operation, all of which will be hereinafter first fully described, and then pointed out in theclaim.

in the drawing, Figure 1 is a side elcvation of a device embodying my invention. Fig. 2 is a longitudinal, sectional view at line a-a of 3, and Fig. 53 a plan view of the device.

Similar numerals of reference, whereever they occur, indicate corresponding parts in all the figures.

1 is a cylinder, made of. any approved material.

2 is a cap fitting upon one end of the tube 1, said cap having perforations 3 therein and being provided with a tubular handpiece 4.

5 is a rod provided with a manipulating' piece 6, this rod extending through the tubular hand-piece 4 and into the cylinder 1, bears a piston 7 on its inner extremity. The piston is provided with perforations 8, and a valve 9, made of leather, or other .suitable material.

10 is a dust receptacle removably secured to the cylinder 1, and having a cover 23 hinged at 11.

12 are catches for holding the covertightly closed, or for releasing it s0 it may turn back upon its hinge. 13 is a spout or mouth piece extending into the dust receptacle through a collar 14 and a perforation 15 in the front Wall of the receptacle 1 0.

16 isa set screw tor holding and adjusting in the cylinder 1 at its union with the dustreceptacle 10. This collar has a. valve Q0 at one side, the dust rcceijitacle, a, straining' device consisting of wire gauze 21, and-coarse cloth 22, or the equivaient.

'The spout .13 extends into the receptacle 10, -ont of contact with the walls thereof excepting` where it enters. The result of this arrangement, shown particularly in Fig. oi the drawing', is to throw the dust against the walls oit' the receptacle, as it enters, and deflect it, Ato the bottom of the rei'septacle.

I have discovered that in order a device of this nature practical and easily operated in general use, it is of theA greatest importance and very essential that means be provided to facilitate the removal of dust directly from the device without. disconnectingl any oit the parts. ri `lieret'oi'e I have provided means in the dust receptacle whereby its contents may be easily, quickly and conveniently removed directly therefrom, and without soiling the hands of the operator. In actual practice I find that in order to prevent any return, or possible escapeof dust through the spout, after entering the sanne, it is of great advantage and I have provided a valve 17 at the end of the spout, thereby preventing' dust from returningI or being' ejected therefrom by any reaction of the means for suction of air.

In operation, the user holds the handpiece G and 'moves the piece 4, carryingthe cylinder and connected parts, with the other and, passing the spout over .the surface to be cleanedas the piston is reciprccated; or the cylinder and connected parts may be held stationary and the piston reciprocated, in accord-ance with the requirements oi" the to make and bears at the other, within Work being done. 1When it is desired to re I move the dust, the cover of the receptacle is thrown back und the receptacle reversed in position, and the air filter may be readily removed for cleaning or replacing. Having now fully described my invention, what I claim as new therein and desire to secure by Letters Patent, is:

A dust collecting implement adapted to be reciprocated over a surfaee' to be cleaned7 comprising the combination -o a rigid suction spout adapted to be moved over a surface to YJoe cleirned, a suction pump, a dust
